One of the world’s richest women’s death remains unexplained as autopsy proved inconclusive after Eva Rausing, the 48-year-old wife of the heir to the £6.5 billion Tetra Pak drinks carton fortune, was found dead by the officers in her home in one of London’s most expensive areas, Belgravia.

The Police has put her husband, Hans Kristian Rausing, the 49-year-old billionaire whose Swedish father helped transform Tetra Pak into a hugely successful manufacturer, in custody, in connection with the death. However he was originally arrested on Monday being suspected of possessing drugs.

The couple had long-running and often public battles against drug addiction. Eva herself supported a number of charities to fight addictions. One such charity, Action on Addiction, acknowledged her “wonderfully generous” support over the years and expressed grief over her sudden death.

Following the inconclusive autopsy, more investigation has been carried out by the officers from the Homicide and Serious Crime division. The police stated, “the death continues to be treated at this time as unexplained.”

Eva Rausing’s family exclaimed they were “deeply saddened by the death of their beloved daughter”. Her parents Tom and Nancy Kemeny proclaimed, “Eva was a devoted wife for 20 years and mother of four much-loved and wonderful children.During her short lifetime she made a huge philanthropic impact, supporting a large number of charitable causes, not only financially, but using her own personal experiences.”

They added, “She bravely fought her health issues for many years. The family is devastated at her death and asks to be given privacy at this difficult time.” “Hans and Marit Rausing and their family are deeply shocked and saddened to hear of the tragic death of their daughter-in-law Eva Louise Rausing. They ask that their privacy be respected at this sad time,” said her husband’s family.
